Four people have died, and hundreds of thousands of homes and businesses are without power in Texas following severe storms that struck the Houston area on Thursday night.

Houston Fire Chief Samuel Peña reported that two people were killed by fallen trees and one in a crane accident, though these causes are preliminary and not officially confirmed. No details were provided about the fourth death.

FBI special agents shot and killed a Utah man Wednesday while attempting to arrest him for allegedly making threats against President Joe Biden ahead of the president’s trip to the state.

The man, Craig Robertson, was facing three federal charges, including threats against the president as well as influencing, impeding and retaliating against federal law enforcement officers by threat. Investigators noted that Robertson appears to owns “a sniper rifle” and several other firearms.

Some of the threats happened just ahead of Biden’s planned trip to Utah on Wednesday evening.

“I HEAR BIDEN IS COMING TO UTAH,” one threat read, according to prosecutors. “DIGGING OUT MY OLD GHILLE SUIT AND CLEANING THE DUST OFF THE M24 SNIPER RIFLE. WELCOM, BUFFOON-IN-CHIEF!”

Robertson also posted online threats in recent months against other Democratic politicians and prosecutors who have brought cases against former President Donald Trump. The case comes amid heightened vitriol aimed at national and local leaders in the lead-up to the 2024 election and what FBI Director Christopher Wray has called an “unprecedented” level of threats against FBI agents.

In a post on Monday Robertson said, “Hey FBI, you still monitoring my social media? Checking so I can be sure to have a loaded gun handy in case you drop by again.”
